APPARATUS FOR UNLOADING SCOWS.

SPECIFICATION forming part of Letters Patent No. 716,105, dated.December 16, 1902. Application 'filerl April 28. 1902. Serial No.104,968. (No model.)

To all whom it mayooncern:

Be itknown that I, JESSE W. RENO, a citizen of the United States ofAmerica, and a resident of the city, county, and State of New York, haveinvented certain new and useful Improvements in Apparatus for UnloadingScows, of which the following is a specification.

My invention relates to improvements in apparatus for unloading anddumpingflatboats or scows, such as are used for the transportation ofdirt, garbage, and the like, where such material is to be thrownoverboard, either for the purpose of filling in or making a convenientdisposition of Waste matter.

. The object of my invention is to produce an apparatus whereby scows,flat-boats, and the like, which are used to convey material which is tobe thrown into the sea, may be unloaded more expeditiously and at lessexpense than by the method or with the apparatus heretofore used.

My invention consists in arranging a series of pipes in close proximityto the deck on which the material of such boats is carried, in providingjet-nozzles in the pipes, and in providing means for forcing underconsiderable pressure a stream of Water through said pipes andjet-nozzles, and thereby washing said material overboard. 7

My invention consists, further, in subdi viding the deck of the scowinto compartments, which compartments are provided with pipes, asaforesaid, and are controlled independently of each other.

In many large seaboard cities it is a practice to convey garbage andwaste material on the deck of flat-boats or scows out to the sea andthrowing such material overboard. It is also common to convey dirtforthe purpose of filling in such places, as where docks are to beerected and the like, with dirt, gravel, (he. 7 In all of thes'ecasesthe method now in use for unloading such material is by means of anordinary shovel, which is laborious, slow, andexpensive.v

By means of my improved method and apparatus scows may be unloaded in arelatively short time and with a relatively small expenditure of labor.

In the drawings accompanying and forming part of this specification,Figure 1 represents a plan view of a scow provided with one form of myapparatus. Fig. 2 represents an end view. Fig. 3 represents a partialcross-section on line a a of Fig. 1. Fig. 4 represents a partiallongitudinal section through the center line of the scow. Fig. 5represents an enlarged view of a portion of one of the pipes 12, showingone of the jetnozzles therein.

The reference characters are used in the same sense in all of thefigures of the drawings and the specification.

Numeral 1 represents the main deck of a seow or a flat-boat. The deckslopes from the center downward toward the outside edge or gunwale andis divided into the transverse compartments 2 by means of the transversepartitions 3.

Numeral 4 represents longitudinal pipes arranged along the apex of thedeck, the length of each pipe being substantially the width of thecompartment in which it is placed.

5 represents a longitudinal pipe or main connected with the pump 6 andconnected with each of the pipes at by means of a vertical connection 7,provided with a valve 8.

9 represents transverse branches connected with the longitudinal pipesat.

10 represents slots or jet-nozzles in the longitudinal pipes 4 andbranches 9, which direct the water from said pipes and. branches ontothe deck of the boat.

11 represents hinged sides to the boat, which are preferably made insections of a length equal to the width of the compartments 2. Thesehinged sides are locked in place, as shown in Fig. 2, in any convenientmanner and serve to increase the carrying capacity of the boat.Preparatory to unloading they are unlocked and let down, as will bereadily understood.

The material carried by boats of the class to which this inventionapplies is not usually homogeneous, and when the Water is turned on thematerial from one side may be carried away earlier than that of theother side. If this were to take place during the whole length of theboat, it would be likely to capsize, and to prevent this I divide thedeck into compartments or segments of such size that it would notmaterially efiect the stability of the boat should all the material fromone side of the segment be removed before any of that on the other side,and by means of the valves 8 I am enabled to operate one or moresegments at a time and to discontinue the operation of any segments atany time, as required.

Having thus described my invention, what I claim is- 1. In an apparatusfor unloading scows, the combination with a deck adapted to carry loosematerial, of a pipe extending along the surface of said deck,jet-nozzles in said pipe directed toward the outer edge of said deck,and means for forcing a powerful stream of water through said pipe and jet-nozzles whereby said material is swept overboard.

2. In an apparatus for unloading scows, the combination with a deck, oftransverse partitions dividing the deck-surface into transversesegments, pipes provided with jet nozzles or openings located on eachsegment, and means of forcing water through the pipes of one or moresegments at a time.

3. In an apparatus for unloadingscows, the combination with a deckadapted to carry loose material inclined from its longitudinal centerline downward toward its outer edge, of a pipe located near and parallelto said longitudinal center line, jet-nozzles in said pipe, and means offorcing water through said pipe and said jet-nozzles, whereby saidmaterial may be washed overboard.

4. In an apparatus for unloading scows, the combination with a deckinclined from the center downward toward its outer edges, of transversepartitions extending above the surface of said deck, dividing it intocompartments, a pipe extending along the ridge of each compartment,having branches at its ends extending parallel to said partitions,jetnozzles in said pipes and branches, a longitudinal main, andindependent connections between said main and the pipes of saidcompartments.

5. In an apparatus for unloading scows, the combination with the deck 1,of the partitions 3, the pump 6, the main 5, the vertical connections 7having the valves 8, and the pipes 4 and 9 provided with the jet-nozzles10, and communicating with vertical connections '7.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JESSE W. RENO.
